BUCKLE.

SPECIFICATION forming part of Letters Patent No. 347,340, dated August1'7, 1886.

Application filed June 16, 1886.

To @ZZ whom it may concern..-

Be it'known that we, JOHN E. GAELE and FRANK M. WILLIAMS, citizens ofthe United States, residing at the city of Grand Rapids, in the countyof Kent and State of Michigan, have invented a new and usefulImprovement in Buckles, of. which the following is a speciiication.

Our invention relates to that class of buckles in which the prongs areso adjusted to the buckleframe in connection with a spiral spring thatit iirmly and safely secures the cloth, and vis readily freed by drawingback on athumb-piece secured with the sliding prongs, then again readilyreadjusts itself and firmly locks the cloth on removing the thumb. Weattain these objects by the mechanism illustrated in the .accompanyingdrawings, in

which- Figure l is aplan or top view of the device, and Fig. 2 shows areversed or under View of the device.

Similar letters refer to similar parts throughout the several views.

2 5 Loops A and B, connected by connectingbars D D, forming aneckbetween the two loops, constitute the frame-work of our buckle, andwhich is cut from a single piece of metal or made from a piece of wirebent upon itself,- as shown in the drawings.

Clamp or band F, to which are firmly secured prongsa a, is secu red tothe neck portion of the buckle-frame D D by means of extendving lugs cc, which clasp upon D D and slide back and forth thereon, so as to admitcloth through loop A. This clamp or band F is projected at the upper endand between the prongs and turned back between D D, forming two rightangles or square hook, d, thus forminga 4o suitable receptacle for theupper end of spring E to restin. The outer or upper side of clamp SerialNo. 205,339. (No model.)

F is made oval, that it mayy fit over the spring E, and at the same timeproduces a prominence that serves as a thumb-piece to draw the clampdown on the spring, as shown in Fig. 1. Spiral spring E is placedbetween connecting-barsD D and under oval portion of clamp F, secured inposition at the bottom on portion B of the frame by a pin, C, passing ashort distance up into the spring, and at the top rests in and 5oagainst the upper end of clamp or band F, a portion of which is turnedback and forms a.v suitable receptacle, d. The object of this spring is,that when adjusted it forces, from its own elasticity, the prongs ortongues a a through the cloth, and causes them to rest upon the outermargin of loop A, and prevents it from slipping or sliding back when notde-` sired, and thus freeing the strap or cloth.

We are aware thatapatent has been granted upon a sliding tongue buckle,but not that there has yet been patented one having a spiral springwhereby the tongues are selfadj ustable, and thus firmly secured; andtherefore We claim as our invention and desire to secure by LettersPatent the device above described, viz:

The combination of a buckle frame com- /posed of loops A B, neck D D,forminga sliding frame, with clamp or band F, provided with prongs auand extending lugs c c,where by the clamp or band F is secured to thebuckle-frame, and spiral spring E, resting on portion'B of the frame andsecured by pin C, and held at the upper end in the clamp or band inposition by receptacle d, substantially as described. ,i
